Open Source

# Digital freedom isn't just for techies. It's for everyone. Join us for a hands-on workshop where you will learn how to adopt Europe-made **and/or** open-source day-to-day applications to gain independence from big tech providers. Concretely: 1. Understand which Europe-made **or** open-source applications exist in the market for *email, calendar, chat, browser, search engine, operating system, etc.* 2. Step-by-step instructions on how to install and configure. You choose which apps you feel comfortable testing! # Agenda 1. Welcome & Introduction (10min) 2. Short documentary on Digital Sovereignty (10min) 3. Hands-on workshop (90min) Together, we can move away from surveillance platforms toward open-source and privacy-friendly alternatives. Europe's digital future depends on choices we make today and it starts with the tools on your phone and computer. ## Inspired by Ghent’s Digital Sovereignty movement Inspired by FOSS workshops that have been thriving in Ghent, this event brings hands-on guidance to help you make the switch, step by step, at your own pace. # What to bring **Preferably**: Laptop. **Optional**: Phone or tablet & USB Stick (8GB) We will work with all types of applications *(email, calendar, chat, browser, search engine, operating system, etc.)* but **you choose** the ones you would like to adopt! # About the organizers This initiative is entirely self-funded, rooted in the belief that understanding our digital world should be open to everyone. ## Carolina Aguilar Carolina is an engineer by training who has spent a career at the intersection of data and artificial intelligence. Deeply committed to European Digital Sovereignty, she hosts this independent workshop to empower others with the knowledge needed to navigate and shape Europe's digital future.

This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept. Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge. ## Requirements * Bring your own laptop (Windows, Linux or Mac) * Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you ! * A strong desire to learn stuff, good mood and some patience !

Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you! After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations. Past questions have been wide and not confined to academic philosophy: What is a genuine friend? Is social media turning us into emotional zombies? Do we lose some of the experience of things by defining them? Are we driven by sex? Is loneliness a personal failure? Is morality relative? **Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.

Let's meet to write ! Schedule : 11:00 - 11:30 am : Presentation tour. Share briefly with the group about your project and your "goal of the day". 11:30 - 13:30 : Let's write ! 13:30 : Conclusion tour. Did you achieve your goal of the day ? See you soon !

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
